Title:
POROUS SILICON-CONTAINING COMPOSITE, CARBON COMPOSITE USING THE SAME, ELECTRODE, LITHIUM BATTERY, AND ELECTRONIC ELEMENT INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2020066574
Kind Code:
A
Abstract:
To provide a porous silicon-containing composite, a carbon composite using the same, an electrode, a lithium battery, and an electronic element including the same.SOLUTION: There is provided a porous silicon-containing composite comprising a porous core containing porous silicon composite secondary particles and a shell containing a first graphene on at least one surface of the porous core, in which the porous silicon composite secondary particle contains an aggregate of two or more silicon composite primary particles and the porous silicon composite secondary particle contains an aggregate of first primary particles containing a first silicon, second primary particles containing a structure, a second graphene on at least one surface of the first primary particles and the second primary particles, and the first primary particle differs from the second primary particle in at least one selected from a shape and an oxidation degree.SELECTED DRAWING: Figure 1
